Activation Lock is designed to prevent anyone else from using an Apple Watch if it's ever lost or stolen.

About Activation Lock on your Apple Watch - Apple Support

Activation Lock is an anti-theft feature that cannot be bypassed. Only the previous owner can remove the lock by using their Apple ID & password. Apple will not help you find the previous owner. If the previous owner cannot or will not remove the lock, then the watch is useless to you or anyone else. Try to get a refund or dispose of the watch properly. In the future, see the 'Before you buy a watch from a third-party' section in:

What to do before you sell, give away, or trade in your Apple Watch, or buy one from someone else - Apple Support

Since you got it at a "bins store" mI hope you didn't spend too much on it. Chalk it up to to experience.

You can’t.

Only the previous owner - who you presumably do not know - can “release” the activation lock.

Return it for a refund.

Hello Series8forum!

Upon reading Chattanoogan’s reply, I have revoked my response to avoid misinformation and confusion.

I cannot immediately withdraw my response altogether, but I will make an attempt to have it removed.

However, I do wish you the best of luck in resolving your issue!
